Griffolyn® Roof Vapor Retarders & Barriers

Made from durable and strong, internally reinforced polyethylene laminates, the Griffolyn^® System withstands extreme temperatures and is highly resistant to punctures and tears. Griffolyn^® Vapor Retarders are available in stock sizes, which are available for immediate shipment. This product can also be manufactured in sizes to meet project requirements up to 200’ × 200’ (61 m × 61 m), greatly reducing in-field seams and the potential for failure.

If building codes require a fire retardant vapor retarder, Reef Industries provides a line of fire rated vapor retarder materials that pass NFPA 701 Large Scale "Standards Methods of Fire Tests for Flame-Retardant Textiles and Films." They have a Class 1 / Class A Flame Spread Rating per UBC-42 and ASTM E-84.
